sharing content over the Content channel receive video over
video channel that is forced to H.263 video.
Default: NO.
ISDN_NUM_OF DIGITS When using ISDN Overlap sending dialing mode, this field
holds the number of digits to be received by the MCU.

ISDN_RESOURCE_POLICY
(ISDN)
The flag value determines how the ISDN B-channels within
configured spans are allocated.
The robustness of the ISDN network can be improved by
allocating channels evenly (load balancing) among the spans,
minimizing the effect of channel loss resulting from the
malfunction of a single span.
Set the flag value to:
•LOAD_BALANCE to allocate channels evenly among all
configured spans.
•FILL_FROM_FIRST_CONFIGURED_SPAN
To allocate all channels on the first configured span before
allocating channels on other spans.
•FILL_FROM_LAST_CONFIGURED_SPAN
To allocate all channels on the last configured span before
allocating channels on other spans.
Default: LOAD_BALANCE
